Abstract

The structure of the emission spectra of ThO2 valence electrons, arising upon excitation with synchrotron radiation near the O 4,5(Th) resonance absorption threshold in the photon energy range 70 < hv < 140 eV, was examined taking into account the structure of the photoelectron spectrum and X-ray O 4,5(Th) absorption spectrum, and also the results of relativistic calculation of the electronic structure of ThO2. The line intensities in the emission spectrum of ThO2 valence electrons in the energy range from 0 to 40 eV considerably increases near the O 4,5(Th) resonance absorption thresholds at 90 and 102 eV. Appearance of this structure reflects the excitation and decay processes involving electrons of outer valence MOs (OVMOs, from 0 to 13 eV) and inner valence MOs (IVMOs, from 13 to 35 eV). These processes occur concurrently with common photoelectron emission processes. As the considered spectra at resonance are associated to a greater extent with giant Coster-Kronig transitions involving electrons of valence and inner shells, these spectra reflect the partial density of states of Th6p and Th5f electrons. The smearing of the structure in the range from ∼13 to 35 eV is attributed to the IVMO formation in this oxide.
